trial of neoadjuvant therapy with paclitaxel and carboplatin in operable locally advanced head and neck cancer patients

Conditions: Head and Neck Squamous Cell Carcinoma

Summary: - objective: primary objective: to evaluate the major pathologic response (mpr) of locally advanced head and neck cancer after paclitaxel and carboplatin-induction chemotherapy followed by surgery. secondary objective: to evaluate the efficacy and safety of induction chemotherapy. outcome metrics: local relapse rate (lrr), relapse-free survival (rfs), overall survival (os), adverse reactions according to ctcae 5.0 exploratory purpose: to evaluate changes in circulating tumor cells (ctc) and immunodynamics before and after paclitaxel and carboplatin-induction chemotherapy through blood, biopsy specimens, and surgical specimen analysis. * background : * chemoradiation (crt) or chemotherapy (induction chemotherapy (ic) + crt) after induction chemotherapy has been performed for locally advanced head and neck cancer that cannot be operated immediately or for organ function preservation. . * the efficacy of induction chemotherapy before chemotherapy has been controversial because the results of several phase 3 clinical studies are inconsistent. at present, it is difficult to assert the superiority of either the addition of induction chemotherapy or radiation therapy alone, but in certain subgroups (advanced n stage such as n2c/n3) induction chemotherapy is a useful option to lower distant metastases. i can do it. * as a result of the tax324 clinical trial, when weekly carboplatin-based chemotherapy or surgery was performed after adjuvant docetaxel + cisplatin + 5fu chemotherapy, overall survival was improved compared to cisplatin + 5fu (hr 0.7, p=0.0058), it resulted in improvement of institutional retention rate (3 year lfs: 52% vs 32%). however, it is difficult to apply this tpf therapy to all patients in actual clinical practice due to the toxicity (neutropenia, nephrotoxicity) and the limitation of anticancer radiation. * in a retrospective study, in the case of adjuvant paclitaxel + carboplatin, there was no difference in progression-free survival compared to tpf (p=0.15), and there was no statistically significant decrease in the local recurrence rate (hr 0.27, p = 0.04). confirmed. * therefore, in this study, when paclitaxel and carboplatin-induction chemotherapy followed by surgery and chemotherapy after surgery, compared to standard tpf-induced chemotherapy, it is expected that the clinical outcome will be improved with less toxicity. * hypothesis: paclitaxel and carboplatin-induction chemotherapy followed by surgery, followed by chemo-radiation after surgery according to standard guidelines compared with the existing standard treatment (tcf), improvement of clinical outcome with less toxicity * study procedure * induction chemotherapy paclitaxel 175mg/m2 + carboplatin auc5 (calculated by cockcroft - gault formula) combination therapy a total of 2 intravenous infusions every 3 weeks surgery performed within 2-9 weeks after induction chemotherapy * surgery the surgery in this study means a complete resection for the purpose of a complete cure, and aims for a minimally invasive surgery.
